What is the mandatory scrapping period for passenger cars?

For household 5-seat passenger cars and 7-seat SUVs, non-commercial small and mini vehicles have no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide them to be scrapped. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial passenger cars, and wheeled special machinery vehicles also have no usage period limit. Commercial vehicles have scrapping periods, as follows: Small and mini taxi passenger cars have a scrapping period of 8 years, medium taxi passenger cars have a scrapping period of 10 years, and large taxi passenger cars have a scrapping period of 12 years. Public transport passenger cars have a scrapping period of 13 years, other small and mini commercial passenger cars have a scrapping period of 10 years, and large and medium commercial passenger cars have a scrapping period of 15 years. Mini commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal should fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, Scrapping Approval Application Form" in duplicate and stamp the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, after verification by the motor vehicle inspection office, if they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to send the vehicle for dismantling with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner should submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection office for verification and signature. The license plates will be reclaimed, and the approval will be processed according to regulations to complete the scrapping registration. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation registration of a motor vehicle, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased vehicle. The application to use the original license plate number must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation registration; (2) The owner must have owned the original vehicle for more than three years.

What are the pros and cons of the Volkswagen Tiguan?

Volkswagen Tiguan's pros and cons are as follows: 1. Cons: Although the size has increased, making it into the midsize SUV category, the price has also risen accordingly. The cabin materials are very typical Volkswagen, with no essential difference in workmanship and materials compared to 100,000-yuan models. The throttle response at low RPMs is somewhat slow, and turbo lag is quite noticeable, resulting in uneven power delivery. 2. Pros: The engine's absolute power is good, with relatively smooth power delivery at mid-range RPMs. It is quite fuel-efficient and easy to drive daily, with light and responsive steering that doesn't make the large body difficult to handle.

What material is the Avalon bumper made of?

Asian Dragon bumpers are made of polypropylene plastic. Here are the advantages of using polypropylene plastic for bumpers: 1. Plastic bumpers are very easy to manufacture in terms of styling and fit best with the car body, making the car's appearance very attractive. Additionally, polypropylene is a very lightweight plastic, which can reduce vehicle weight and thereby lower fuel consumption. 2. The manufacturing cost is relatively low, which can reduce the overall cost of the vehicle. On a car, the front and rear bumpers are the most prone to damage. If the bumper were made of iron, repairs would be much more complicated, as correcting metal sheet parts is more complex than plastic parts.

What are the differences between National 5 and National 6 environmental standards?

The differences between National 5 (China 5) and National 6 (China 6) emission standards are as follows: Different emission standards: The National 6 emission standards are more than 30% stricter than National 5. Excluding the influence of driving conditions and testing, gasoline vehicles under National 6 reduce carbon monoxide emissions by 50%, total hydrocarbons and non-methane hydrocarbons by 50%, and nitrogen oxide emissions by 42%. Different implementation times: The National 5 standard was implemented nationwide on January 1, 2017. National 6 has been in effect since July 1, 2019. Different principles: Under National 5, diesel and gasoline vehicles had different emission standards, but National 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing authorities: National 5 was issued by the Ministry of Environmental Protection, while National 6 was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: National 5 is denoted by "V," while National 6 is denoted by "VI." Different monitoring requirements for plug-in hybrid electric vehicles (PHEVs): Compared to National 5, National 6 has enhanced monitoring requirements for PHEVs, including energy storage systems, thermal management systems, regenerative braking, drive motors, generators, and other regulatory aspects. Different prices: National 6 vehicles are equipped with additional components compared to National 5. Moreover, automakers incur extra costs for vehicle certification, testing, and production, resulting in significantly higher prices for National 6 vehicles than National 5 vehicles. Different scrapping timelines: Although the government has abolished mandatory scrapping timelines, older vehicles may be banned from roads, effectively rendering them scrapped. For example, a National 5 vehicle purchased in January 2019 and a National 6 vehicle purchased at the same time may both have a 15-year registration period, but their actual usability will differ. For instance, as of now, National 3 vehicles from 2010 and National 4 vehicles from the same year can still operate in Beijing, but many older vehicles are effectively scrapped due to increasing city restrictions. Thus, even for vehicles of the same age, their usable lifespans differ. National 5 emission limits are as follows: Gasoline vehicles must not exceed 1,000 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbons must not exceed 68 mg per kilometer, nitrogen oxides must not exceed 60 mg per kilometer, and PM (particulate matter) must not exceed 4.5 mg per kilometer. National 6 has two sub-standards: National 6a and National 6b, as follows: National 6a emission limits: Gasoline vehicles must not exceed 700 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbons must not exceed 68 mg per kilometer, nitrogen oxides must not exceed 60 mg per kilometer, and PM must not exceed 4.5 mg per kilometer. National 6b emission limits: Gasoline vehicles must not exceed 500 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbons must not exceed 35 mg per kilometer, nitrogen oxides must not exceed 35 mg per kilometer, and PM must not exceed 3 mg per kilometer. Due to the National 6 emission policy, although National 5 vehicles are not currently restricted in normal use (no driving bans or license plate restrictions), their resale value will be significantly affected. For truck owners, if they purchase a truck on loan for freight transport, the depreciation of the vehicle after paying off the loan directly impacts their net profit during that period. A higher residual value means greater earnings for the owner. From this perspective, National 6 vehicles, with longer usability and better road access, offer more advantages.

MISTRA Sudden Braking Noise with Rebound?

When the MISTRA suddenly brakes, there is a stuttering abnormal noise, and the brake pedal rebounds. This could be caused by an issue with the gap between the brake pads and discs. Below is relevant information: 1. Anti-lock Braking System (ABS): Its function is to automatically adjust the braking force during vehicle braking, preventing wheel lock-up and maintaining a rolling-sliding state to ensure maximum adhesion between the wheels and the road surface. 2. Four-Channel System: The four-channel ABS has four wheel speed sensors, with a brake pressure regulator device installed in the pipeline leading to each of the four wheel brake cylinders, enabling independent regulation and forming a four-channel control configuration.
